Simultaneous photocatalysis of methyl orange and Cr(Ⅵ) in water by TiO_2

JIANG Li-juan,WANG Ya-jun,FENG Chang-gen(State Key Laboratory of Explosion Science and Technology,Beijing Institute of Technology,Beijing 100081,China)  
This paper is engaged in a study of photocatalysis of methyl orange and Cr(VI) in water by TiO2,a kind of chemical method,which turned to be a promising process of controlling environmental pollution because of its simplicity,low cost,high efficiency and so on.Furthermore,photocatalysis is an effective way to deal with both organic contamination and heavy metal ionization.In many of the photocatalytic reagents,chemical researchers prefer to take interest in TiO2 for it is nontoxic and enjoys excellent stability and therefore serves as a highly promising raw material source.It is due to all the above reasons and many more others that the present authors take a great interest in pursuing a study of the coexistence of photocatalytic systems both of organic pollution and heavy ions effects.That is,to study the simultaneous photocatalytic oxidation of methyl orange(MO) and photocatalytic reduction of Cr(VI) in water by self-made TiO2 with sol-gel method.Our purpose is to achieve significant enhancement of degradation of MO and reduction of Cr(VI) both by UV-irradiation and visible light-irradiation in the acid condition.The results show that there has been existing a strong synergistic effect in the composite system,and,therefore,photocatalytic efficiency in composite system can be made significantly higher than the photocatalytic efficiency in its singular counterpart.In this paper,we also want to discuss the influential factors of photocatalysis in the mixed system,such as the mass ratio of MO and Cr(VI),pH,light wavelength,the dosage of TiO2,and calcination temperature.As is known,when the mass ratio of Cr(VI)/MO equals 2/3-2/5,the synergistic effect is likely to be the best.Besides,the calcination temperature of TiO2,light wavelength and pH are also the important influential factors.In case the mass ratio of Cr(VI)/MO equals 2/3-2/5 in the mixed system with pH 1,the two pollutants can be totally eliminated in 40 min for MO and 70 min for Cr(VI) under the radiation of visible-light(λ≥420 nm) with 1.6 g/L TiO2 of calcination temperature of 550 ℃,and the two pollutants can also be completely eliminated in 30 min for MO and 60 min for Cr(VI) under the radiation of UV-irradiation(λ≥365 nm) under some other conditions of the same nature.
